Ruben Amorim urged not to repeat Garnacho mistake as Sir Alex’s Mainoo warning resurfaces

But Garnacho eventually left for Chelsea in the summer following a breakdown in his relationship with Amorim late in the 2024-25 season.

Ferguson’s comments came when he was asked about Mainoo and Garnacho’s rise within the first team. His words carried significant weight regarding both players.

Speaking to TikTok star Jamal Niaz in 2024, Ferguson said: “It’s the foundation, isn’t it? They’re young. What they’re showing at the moment, the composure and confidence to play in the first team, and not be daunted by it.”

“In a way, it shows you the kind of courage they have. It’s a distinction in human beings, some have the will to be that [fearless at a young age].”

Ruben Amorim can’t treat Kobbie Mainoo the same way he did Alejandro Garnacho

Ruben Amorim’s falling out with Alejandro Garnacho stemmed from the winger’s outspoken comments following United’s 1-0 final defeat to Tottenham in May.

After those remarks, Garnacho’s days at Old Trafford were numbered, and he eventually made the switch to Stamford Bridge.

Kobbie Mainoo has also seen his influence reduced this season. Amorim has preferred using Bruno Fernandes in a deeper midfield role, limiting Mainoo’s opportunities.

Mainoo, now 20, considered leaving Old Trafford over the summer in search of more playing time after dropping out of the starting lineup.

He stayed on for this campaign and remains a favourite among fans. However, Amorim needs to carve out a clearer role for him within the squad if he wants to avoid another backlash.

If not, Ferguson may have warned about two players integral to the “heart and soul” of United who ended up leaving during Amorim’s tenure.
